Mervyn King

Mervyn King served as Governor of the Bank of England from 2003 to 2013. His tenure included the 2007 Northern Rock crisis — the first bank run in Britain in 150 years — and the subsequent financial crisis response. King was initially criticized for being slow to respond but ultimately oversaw large-scale emergency liquidity operations and quantitative easing. After leaving the BoE, he wrote "The End of Alchemy" (2016), arguing that the financial system's fundamental fragility has not been resolved by post-crisis reforms. He was made a life peer as Baron King of Lothbury. Before becoming governor, King was Deputy Governor and Chief Economist at the Bank and a professor of economics at the London School of Economics. His academic framework emphasized the distinction between risk — events that can be probabilistically modeled — and radical uncertainty, which cannot. This distinction informed his later critique of post-crisis regulatory reform. In "The End of Alchemy," he proposed replacing lender-of-last-resort facilities with a system of "pawnbroker for all seasons," where banks pre-pledge collateral. His work on uncertainty and monetary economics has influenced subsequent scholarship on central bank communication and decision-making under fundamental uncertainty.
